Potential GPR feedstocks include all organic materials such as:
- Biomass and organic based material fraction of MSW.
- Municipal sewage sludge.
- Urban wood waste in all forms, including coated and treated lumber (e.g. wooden railroad ties, pulp, construction and storm demolition).
- Forestry biomass regardless of species or part of the tree.
- Agricultural wastes (rendering waste, chicken litter, sugar cane bagasse, etc.).
- Industrial and commercial products such as plastic and tires.
- Industrial sludge, including hazardous organic waste.
GPR also provides the flexibility of ‘blending’ organic materials with differing chemical compositions “on the fly” without having to alter production line parameters, or even close down production.
GPR systems are scalable through the addition of parallel reactors. Process plants are designed to fit the quantity of readily available inputs - large or small - not the other way round. GPR plants are, by chemical industry standards, straightforward in design and operation. Uptimes greater than 90% are expected in individual reactors and have been achieved in previous demonstration plants. Multiple production lines with built in redundancy would enable virtual 100% uptime.
Higher Conversion Efficiencies
The nature and characteristics of the GPR syngas lend themselves to more efficient power generation than typical waste to energy technologies, thereby significantly reducing GHG’s per unit of energy produced.
Carbon Credits & Government Sponsored Support
The NES GPR solution will generate significant carbon credits through the conversion process and the production of the fuel, which may have future value for the customer. In addition, there are numerous Government financial programs at Federal, Provincial/Sate and Municipality levels available for commercial scale facilities, which have not be included in the business models prepared by NES. The NES GPR solution is profitable without factoring in these programs.
The GPR syngas requires less air to complete the combustion cycle than natural gas – i.e. more of the fuel and less nitrogen from the air is introduced into the combustion process, increasing the syngas efficiency. So, while the GPR syngas contains approx. 90% of the energy content of natural gas, its “combustion power” approaches that of natural gas, allowing for little or no de-rating of the gas turbine equipment.
